Abstract (en)
An illumination system including at least one light source which can be a laser, a reflection cover which can be a parabolic mirror, a wavelength conversion element which can be a phosphor, and a filter element which can be a color weel is provided. A focal point of the reflection cover is disposed on an extension line of a transmission path of an excitation beam provided by the light source, and an opening of the reflection cover is adjacent to the focal point and can be at the apex of the parabolic mirror. The wavelength conversion element penetrates through the opening, and has a light-action region. The light-action region is disposed on the transmission path of the excitation beam, and converts the excitation beam into a conversion beam. The reflection cover is disposed on a transmission path of the conversion beam. The filter element is disposed on a transmission path of the conversion beam from the reflection cover. The conversion beam from the reflection cover is obliquely incident to the filter element, and the filter element filters the conversion beam.
